Vehicular visual recognition device
View Patent ↗An electronic outer mirror device includes a camera to assist visual recognition by an occupant of a vehicle, a visor configured to house the camera, and a base configured to support the visor such that the visor is capable of moving. The electronic outer mirror device further includes a first tube that is provided on the base side and through which passes a fluid to be ejected onto the camera in order to secure a field of view of the camera. The electronic outer mirror device further includes a second tube that is provided on the visor side such that when the visor is positioned at a predetermined position with respect to the base a base side of the second tube is connected to the first tube so as to enable passage of the fluid from the first tube, and when the visor is positioned at a different position from the predetermined position with respect to the base the base side of the second tube is disconnected from the first tube.
1. A vehicular visual recognition device comprising:
a visual recognition section configured to assist visual recognition by an occupant of a vehicle;
a housing body configured to house the visual recognition section;
a support body configured to support the housing body such that the housing body is capable of moving;
a first fluid passageway that is provided at the support body side and through which passes a fluid to be ejected onto the visual recognition section in order to secure a field of view of the visual recognition section; and
a second fluid passageway that is provided at the housing body side such that: when the housing body is positioned at a predetermined position with
respect to the support body, a support body side of the second fluid passageway is connected to the first fluid passageway so as to enable passage of the fluid from the first fluid passageway, and
when the housing body is positioned at a different position from the predetermined position with respect to the support body, the support body side of the second fluid passageway is disconnected from the first fluid passageway.
2. The vehicular visual recognition device of claim 1 , wherein, when the
housing body is positioned at a different position from the predetermined position with respect to the support body, the support body side of the second fluid passageway is closed off by part of the support body.
3. The vehicular visual recognition device of claim 1 , wherein,
in a state in which the support body side of the second fluid passageway is closed off by a part of the support body, when the housing body is positioned at a different position from the predetermined position with respect to the support body, a housing body side of the first fluid passageway is covered by a part of the housing body.
4. The vehicular visual recognition device of claim 1 , wherein:
the support body includes a main support body and a support body cover configured to cover the main support body,
a tube-shaped first connection portion to which the first fluid passageway is connected is provided at the support body cover,
a tube-shaped second connection portion to which the second fluid passageway is connected is provided at the housing body,
the first connection portion and the second connection portion are disposed coaxially to one another when the housing body is positioned at the predetermined position with respect to the support body, and
the second connection portion is disposed at a different position that is not coaxial to the first connection portion when the housing body is positioned at a different position from the predetermined position with respect to the support body.
5. The vehicular visual recognition device of claim 4 , wherein
a tube-shaped seal member is provided at a peripheral edge of the second connection portion of the housing body, and an end portion on a support body cover side of the seal member is configured to abut the support body cover.
6. The vehicular visual recognition device of claim 1 , wherein
a foreign matter suppressing member is provided between the housing body and the support body in order to suppress ingress of foreign matter into the first fluid passageway.
